and both pairs of wings are crossed by a narrow blackish 

 band. This species is quite widely distributed ; but is quite 

 rare in most places. 



The other representative of this family found in the 

 United States is Lacosoma chiridota (Lac-o-so'ma chir-i-do'- 

 ta). This species is even more rare than the preceding; it is 

 somewhat smaller, and dark yellowish brown in color ; but 

 its general appearance is very similar. The venation of the 

 wings is also similar to that of Cicinnns except that vein 

 VIII of the hind wing is wanting. 



Family LASIOCAMPID^E (Las-i-o-cam'pi-dae). 



The Lasiocampids {Las-i-o-cam 'pids). 



This family includes the Tent-caterpillars and the Lap- 

 pet-caterpillars. The adults are stout-bodied, hairy moths of 

 medium size. The antennae 

 are pectinated in both sexes, 

 and are from one fourth to 

 one half as long as the front 

 wings ; the teeth of the an- 

 tennae of the male are usu- 

 ally much longer than those 

 of the female. The ocelli arc- 

 wanting ; and the palpi are 

 usually short and woolly. 

 But the most distinctive char- 

 acteristic is found in the 

 wings. The frenulum is want- 

 ing, there being instead, as 

 in the Saturniina, a largely- 

 expanded humeral angle of 

 the hind wings. But these 

 moths differ from the Satur- 

 niina in having CubitUS ap- FlG - 44I-— Wings of Clisiocampa americana.
